Kubernetes缩小特定Pod [英] Kubernetes scale down specific pods

问题描述

我有一组Pod运行命令，可能需要花费几秒钟的时间.有一个过程可以跟踪打开的请求和请求在哪个Pod上运行.我希望在缩小Pod时使用该信息-通过指定要尝试退出的Pod或指定要关闭的Pod.更改副本数时是否可以指定这种类型的信息，例如我想要X个副本，请尝试不要杀死我在Pod A，B，C上长时间运行的任务?

I have a set of Pods running commands that can take up to a couple seconds. There is a process that keeps track of open request & which Pod the request is running on. I'd like the use that information when scaling down pods - either by specifying which pods to try to leave up, or specifying which pods to shut down. Is it possible to specify this type of information when changing the # of replicas, e.g. I want X replicas, try not to kill my long running tasks on pods A, B, C?

推荐答案

我一直在寻找自己的解决方案，但我也找不到开箱即用的解决方案. 但是，可能有一种解决方法(如果您可以测试并确认，将会非常喜欢)

i've been looking for a solution to this myself, and i also can't find one out of the box. however, there might be a workaround (would love it if you could test and confirm)

步骤:
1.删​​除复制控制器
2.删除所需的X个豆荚
3.重新创建大小为X的复制控制器

steps:
1. delete replication controller
2. delete X desired pods
3. recreate replication controller of size X
